Yes, you usually need a permit to remodel your home in Vancouver and Clark County when the work changes walls, structure, plumbing, electrical, mechanical systems, or the footprint of the house. Cosmetic updates like painting, new carpet, cabinets, and countertops generally do not require one.
That’s the short version. The details depend on what you’re changing and which jurisdiction your home sits in, so this guide walks through what the City of Vancouver and Clark County actually require, what’s exempt, and what can happen if a project skips the process.

When do you need a permit for remodeling?
You need a permit for remodeling whenever the work changes how the house is built or how its systems run, not just how it looks. Both Clark County and the City of Vancouver list the same core triggers:
- Additions, alterations, and remodels to existing structures
- Adding or removing walls
- Changing the footprint of the house in any way, including adding a second story
- Converting a basement, attic, or garage into living space
- Adding a garage, carport, deck, or patio cover
- Adding or replacing a driveway or RV pad
Dollar value doesn’t get you out of it. Structural, plumbing, and mechanical work needs a permit regardless of what it costs.
Even small changes can count. Taking out a non-load-bearing wall to turn two bedrooms into one still falls under a county alteration permit. And if you’re not sure whether a wall is structural, I treat it as structural until someone has verified otherwise.
What do you need a permit for when remodeling a house?
Most remodeling beyond cosmetic updates needs at least a building permit, and many projects also need plumbing, mechanical, or electrical approvals. Here’s how that plays out room by room.
Kitchens. Replacing cabinets and countertops on their own doesn’t need a permit. Moving the sink or range, running new plumbing or gas lines, adding circuits, or taking out a wall does. Most full kitchen remodels cross at least one of those lines.
Bathrooms. Surface updates like paint and finishes don’t need a permit. Relocating a tub, shower, toilet, or vanity—or adding plumbing or electrical—does. In Clark County, installing any new plumbing fixture requires a plumbing permit.
Additions and second stories. Always. For additions, Clark County folds the required plumbing and mechanical permits into the main permit. In Vancouver, expect to submit a site plan, foundation plan, floor plan, elevations, and framing plans.
Garage, basement, and attic conversions. Turning unfinished space into living space requires a permit, because the space now has to meet code for things like egress, insulation, and electrical.
Decks, patio covers, and outdoor living. In general, decks need permits. In Clark County, a deck is exempt only if it’s 200 square feet or less, no more than 30 inches above grade at any point, not attached to the house, and not serving a required exit door. Patio covers need a permit. Concrete patio slabs on the ground generally don’t.
Windows, siding, and roofing. In unincorporated Clark County, replacing windows or siding requires a permit, and re-roofing permits are required for all buildings. Rules in the cities can differ, so check with yours.
When are building permits required for remodeling in Vancouver and the rest of Clark County?
Building permits are required for remodeling throughout Clark County, but which office issues yours depends on where your home sits.
- City of Vancouver: Residential Building Permits cover additions, remodels, and the other work above. The city offers free 30-minute virtual appointments with permit center staff, which are worth using before you finalize plans. Permit specialists can be reached at 360-487-7833.
- Unincorporated Clark County: Clark County Community Development issues residential permits for homes outside city limits. Their number is 564-397-2375.
- Other cities: Camas, Washougal, Battle Ground, Ridgefield, and the county’s other municipalities set their own permit processes, so confirm with your city before you start.

Electrical, plumbing, and mechanical permits
Electrical, plumbing, and mechanical work often needs its own approval, though on a bigger remodel it’s frequently folded into the main building permit.
- In Vancouver: Trade work that’s part of a remodel is included in your residential building permit. Small standalone jobs, like a repair or replacement, use a separate trade permit through the city’s Online Permit Center.
- In unincorporated Clark County: The county doesn’t issue electrical permits. Those come from the Washington State Department of Labor & Industries (L&I). Lawn sprinklers and wood stoves also need separate permits.
Washington requires a permit and an inspection for electrical work, with a few exceptions. If you hire a licensed electrical contractor, the contractor buys the permit and schedules the inspection.
Remodeling work that doesn't need a permit
Cosmetic and maintenance work generally doesn’t need a permit. In unincorporated Clark County, that includes:
- Painting, carpeting, cabinets, countertops, and similar finish work
- Fences 7 feet tall or less
- Sheds 200 square feet or less
- Decks 30 inches or less above grade (except when used for a hot tub or pool)
- Concrete patio slabs on the ground
No permit doesn’t mean no rules. Exempt work still has to meet building code and local requirements like setbacks and height limits.
What happens if you skip a remodeling permit?
Skipping a required permit can cost far more than the permit would have. Unpermitted work tends to surface when you sell, refinance, or file an insurance claim, and buyers and their agents often ask for permit history.
It can also affect your coverage. L&I warns that your insurance could be jeopardized if there’s a fire after electrical work that wasn’t permitted and inspected.
And fixing it later is harder than doing it right the first time. In Vancouver, for example, unpermitted construction goes through a field evaluation, where inspectors determine what permits are needed. In many cases, you’ll have to pull a retroactive remodel permit to complete and inspect the corrective work.
Why permits are worth it, and a tax break many homeowners miss
A permit means a second set of eyes checks your project against code, with inspections at key stages. That protects your safety, your investment, and your resale value.
There’s a financial upside too. Under Clark County’s Homeowner’s Remodel Exemption, owners of detached single-family homes who make major additions or remodels may be eligible for property tax relief of up to 30% of the new value for up to three years. The application requires the building permit number for the work and must be filed with the Assessor’s Office before construction is completed. Normal maintenance like painting and roof repair doesn’t qualify, so ask the Assessor’s Office whether your project does.
Who handles permits on a design-build remodel?
On a design-build project, permitting should be part of the plan from day one, not something a homeowner has to coordinate between a designer, an engineer, and a contractor. Permit review time is also one of the biggest factors in a remodel schedule.
That’s how we work at Black Cat Design Build. Because design and construction are under one roof, we plan for permits while the design is still taking shape, so the drawings, the budget, and the timeline all account for them. If you want to understand how that differs from hiring a designer and a general contractor separately, I wrote about it in design-build vs. general contractor.
Remodeling permit FAQs
Yes, if the remodel moves walls, plumbing, gas, or electrical, which most full kitchen remodels do. Replacing only cabinets and countertops generally doesn’t require one.
Yes, if you’re relocating fixtures, adding plumbing or electrical, or changing walls. Paint and surface finishes alone generally don’t need one. In Clark County, installing a new plumbing fixture requires a plumbing permit.
Yes. Both Clark County and the City of Vancouver list adding or removing walls as permit work. Even a non-load-bearing wall falls under a county alteration permit.
